Industrial iron ore production and mid-century urban development define this portion of the Marquette Range. The southern corridor is densely packed with the infrastructure of Ishpeming and Negaunee, where the Ishpeming City Boundary meets extensive mining operations. Significant sites like Mather Mine A and the Cambria-Jackson Mine sit alongside the rail networks of the Chicago and North Western and Lake Superior and Ishpeming railroads, which facilitated the movement of Michigan ore.
